Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
The answer is 10√3 because
10√3 is equal to approximately 17.32051 and the formula for finding the area of a square is length multipled by width so 10√3 x 10√3 is equal to 300 or 17.32051 x 17.32051 is equal to 300
The necessary formulas to get the area of a circle’s segment are the area of the circle’s sector and the triangle it is bounded by.
Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.
The formula of the area of a circle’s sector is:Area of Sector =

x (radius of circle)²
While the formula for the area of a triangle is:Area of Triangle =

x base of triangle x height of triangle
The complex conjugate of a + bi is a – bi, and similarly the complex conjugate of <em><u>a – bi is a + bi. </u></em>
Answer:
x=
1/2
and y=3
Step-by-step explanation:
Let's solve your system by substitution.
y=10x−2;2x+y=4
Step: Solvey=10x−2for y:
y=10x−2
Step: Substitute10x−2foryin2x+y=4:
2x+y=4
2x+10x−2=4
12x−2=4(Simplify both sides of the equation)
12x−2+2=4+2(Add 2 to both sides)
12x=6
12x

(Divide both sides by 12)
x=
